The measure of the space inside a 2d figure is called

an area

Step-by-step explanation:

A two-dimensional (2D) figure is like drawing on a sheet of paper. It has some width and some length, but no height.

So, you cannot calculate its volume, since it has only 2 dimensions, a volume requires 3 dimensions.

The only spacial measure you can do on a two-dimensional figure is its area (basically length * width, if we talk about a rectangle, other forms have different calculation methods).

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
